Brief Title

InterLeukin-7 to Improve Clinical Outcomes in Lymphopenic Patients With COVID-19 Infection ( ILIAD-7-US-O )

Official Title

A Multicenter, Randomized, Double-blinded Placebo-controlled Study of Recombinant Interleukin-7 (CYT107) for Immune Restoration of Hospitalized Lymphopenic Patients With Coronavirus COVID-19 Infection. US Oncology Cohort

Brief Summary

      Comparison of the effects of CYT107 vs Placebo administered IM at 10μg/kg twice a week for
      three weeks on immune reconstitution of lymphopenic COVID-19 patients

Detailed Description

      Approximately forty-eight (48) participants will be randomized 1:1 to receive

      (a) Intramuscular (IM) administration of CYT107 at 10 μg/kg followed, after 72hrs of
      observation, by 10 μg/kg twice a week for 3 weeks (maximum 7 administrations adjusted to
      patient's length of stay in the hospital) or (b) Intramuscular (IM) placebo (normal saline)
      at the same frequency.

      The aim of the study is to test the ability of CYT107 to produce an immune reconstitution of
      these patients and observe possible association with a clinical improvement.

      This cohort is dedicated to oncology patients

Study Phase

Phase 2

Study Type


Primary Outcome

Improvement of the absolute lymphocyte count (ALC) of lymphopenic (ALC≤1000/mm3) COVID-19 infected participants out to approximately 30 days following initial Study drug administration or Hospital discharge (HD), whichever occurs first

Secondary Outcome

 To obtain "clinical improvement" as defined by an improvement in a 11-points WHO score for Clinical Assessment, through day 30 or HD.

             physician expects life expectancy due to the underlying malignancy to be less than 6

          6. Patients who received CAR-T cell therapy within the past 30 days or with unresolved
             cytokine release syndrome (CRS) or immune effector cell-associated neurotoxicity
             syndrome (ICANS)
